Branson GMX-20 MA and GMX-HP ultrasonic metal spot welders can be used for high-precision welding of battery foils to tabs, wire terminals to connectors, and are suitable for applications such as automotive electrical systems, electric vehicles, batteries and battery packs, and power storage systems. Further highlighting Branson''s welding solutions in electronic assembly, including
Battery Pack Welders. Weld electrical interconnections within systems such as battery packs with the ease of using a stapler. Sonics'' new UBPW ultrasonic welder can be either hand-operated, suspended from a counterweight system (as shown), or rigid-mounted within a robotic or other type of automated system. A horizontally-oriented version is
Selection of the most suitable technology and process is based on two main factors: tab thickness and material. Resistance spot welding, micro-TIG welding, and laser welding technologies each have specific features that align well to these joining needs.
Spot welding strips and tabs onto batteries to create interconnects and large battery pack assemblies using Resistance Welding or Laser Welding. Send your sample to one of our technology centers in Europe for an evaluation. We will
At this amplitude, the welding process can use up to 5000 W of available power and up to 80 microns of motion (amplitude). 20-KHz ultrasonic metal welding applications include large battery packs for electric cars, battery packs for special vehicles (specialized mining vehicles, large drones, etc.). Applications like these might use prismatic batteries that can join foils from up to
Since the 1990s, ultrasonic metal welding has been widely used by battery and EV makers because it is able to bond very thin materials — down to 5 µm foils — and can do so in assemblies of 100 layers or more. This capability is essential to successful assembly of high-power lithium batteries and super capacitors.
These factors drive the range of techniques for constructing a battery pack, from resistive and ultrasonic welding to micro arc welders, highpower lasers and even high magnetic fields. The choice also varies with the type of cell, whether it be cylindrical, pouch or prismatic.
The quality of the welding here will directly affect the reliability of the quality of the lithium-ion battery pack used as a power source for electric vehicles. In addition, due to the relative particularity of lithium-ion battery, the welding technology has also put forward high requirements. If the welding strength is weak, the internal

Welding is a vitally important family of joining techniques for EV battery systems. A large battery might need thousands of individual connections, joining the positive and negative terminals of cells together in combinations of parallel and series blocks to form modules and packs of the required voltage and capacity.
Whether to power our latest portable electronic device, power tool, or hybrid/electric vehicle, the removable battery pack is essential to our everyday lives. Tab-to-terminal connection is one of the key battery pack welding applications.

“We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech. “If the packs or the overall volume are smaller, then resistance welding is often used. Micro-TIG comes up for specialised battery packs with low-volume production.
Micro-TIG is best suited for tab-to-busbar welding for low to high capacity packs. For more information read Battery Welding Solutions Using Laser & Resistance Technologies. Battery pack welding. The right technology for your job depends on factors including materials, part accessibility, throughput, and budget.
Of these, laser and ultrasonic welding processes dominate in EV battery manufacture – with laser welding the preferred solution for mass production – and continue to be improved and refined. “We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech.
“In these situations, cooperative development and reliable relationships are of high value.” While there many kinds of welding, in EV battery applications the most common are resistance welding and laser welding, along with ultrasonic welding and wire bonding, and benefit from standardisation for mass production.
